Application meld November 8, y11109. SerilNo. 5136,01()- To all whom 'itmay concern? Be it known that l. CHARLES J. OLSON, citizen of the UnitedStates, residing at Muskegon, in the county of Muskegon and State ofMiohigen, haveinvented certain new and `useful Improvements .in RotaryMotors, of which the-following is a specification.

rIhis invention relates to. rotar)r motors und has for its object toprovide a strong, durable, compact and -throughly eticient machine ofthis character, capable of being Opf erated by compressed air, steam, orother uotuating fluid, and which muy be used with equally good resultsfor operating :L pneumatic drill, or as a niotorfor driving (litterentkinds of machinery.

A further object is to provide a rotary motor, the construction of whichis such that the severaflfbarts thereof are evenly balanced, thusinsuring a smooth continuous movement of the rotors, and consequentl)Tincreasing theeflioienov of the machine.

A still further object of the invention is generally to improve thisclass of devices so` as to increase their utility, durability. ond

Further objects and advantages will appear in the descrii'ition, itbeing. understood thetvariousv changes in form, proportions and minordetails of construction may be resorted to within the scope of theappended olziims.

For a full understanding of the invention )reference is to be'had to thefollowingl Figure 1.- ,is a persnective v'iewiof o ro'tary transversesection xil-viewftelten on' theyline 343 of Fig.` Zand looking 1n vthe'direction c 4iso. .similar-.view .teken on -thelnie .11s-4o Fig. 2 'andlooking .in\ the directio'xrof the arrow. -I'Fig is fan e117' .I argeddetail sec-tional view of al'portion of 'the cesing.

The improved motor forming thesubjectmatter ot the present inventioncomprises o. casing or housing 5 preferably' substuniially cylindricalin sha e, andl formed'ot a plurality, of indepe ent sections 6 yheld inassembled position by tie-rods or bolts .7 piero ing the opposite heads8 and 9 of the easing.

Interposed between the casing sections 6 are a plurality of transversepartitions 10 defining intermediate compartncnts 11 in which are mountedfor rotation a plurality of rot-ors 12, the latter bei-ng keyed o rotherwise fixed to a centrally disposed driving shaft 13.

The Casin or housin. 5 is provided with oppositely isposed enlargements.14; each plerced by an `.nlet port 15 and exhsustp'ort 16, there beingauxiliary ports 17 formed in suitable turning plugs 52' threaded in theeasing sections. and through 'which compressedl air or other actuatingfluid is ad- .mitted to the compartments 11. Auxiliary port-s 18 areformed in the casing sections to permit the/passage of the exhauststezun from the compartments 11 to the ports 16 and thence through theopening -or port 18' to the atmosphere.

The rotors 12 a'r'e preferably of irregular shape and are 'each providedwith peripheral .recesses 19 in which ,are pvotolly mounted at 20-blades or pistons 21', there being aishoulder 22 formed by one wall ofeachirecess 19 furthe purpose of limiting the swing ing inox-'ement ofthe adjacent piston. The pistonsfl are normally and lyieldebly sup.-

One wall of each of the recesses 2B is inclined or beveled in suoli amanner as to produce a stop shoulder 31 adapted to receive the impact ofthe adjacent abutment thereof, there beingsutable coi springsBQ seatedvin sockets formed in the enlargements 1 4, and bearing against the'adjacentabutinentsO for normally 'and yieldablysupporting the activeends ofsaid abutments movement of the rotors 12.

Attention is here 'called to the fact that the inner wall of eachenlargement-1.4 is provided with an irregular or cam face 33 which by'engagement with the/active ends ofthe swinging blades or pistons 21serve to gradually close the latter and thus'preyent injury to-tbe'sameby reason of a sudden jar or vibration, which would naturally result ifthe pistons or blades 21 were closed abruptly. The projecting'portrions34 ofthe rotors perform the-same function with reference to tbe swingingblades or abntments to cause the gradualclos ing of said abutments whenthe members 12 are rotated.

The rotors 12 are to the driving sha slight movement of one relative tothe othert and Vthus preventbinding or wedgingaction between the parts.

Then 'the motor'is employed for operat- 'ing,' the bit of a pneumaticdrill, an inlet piped?)A is preferably extendedacross the head 8 ofthecesing and operatively connected 'hvith the inlet ports 15 so as tbforni in `effect a 'handle by means lof which the device may bereferably loosely keyed A supply pipe 36 communicates with une end'of-thc inlet with i-turning plug af similar valve 37 means of whicbthesupplyocompresse air to tlie''compartments .11; may

A capthe casing by the tiebolts or tastenn devices 7 for the'piir ose'of protecting t e gearing, one end o.. the' cap being provided with an'annular flange 50, the. interiorwall's of which are threaded forengagement with a. correspondingly threaded late orclosure 51. Thecy'lindrical enlarge- -ment 41 .ofthe spindle39 is provided with anannular lip or flange 59. spaced from. the head or closure 51 to form anintermediate chamber or compartment for the reception of packing 53,there being anti-friction balls ieee 49v is preferably secured to the orrollers 54 interposed between the flange 521and the adjacent portion ofthe cap 49 for the purpose of reducing friction between arts.

T us it will be seen that when! the cock or valve 37 is opened, air.under pressure will pass through the-"inlet ports. 1.5 and nie'nts 411,and being confined between the pistons 21'and abutmeits 30 will rotatethe 12 in the direction indicated by the arrow in Fig. 3 of the"drawings, vthe compressed air being' exhausted vthrough the ports 16 and1'8 `in the 'manner before described.
